Mark Shannon <m...@hotpy.org> added the comment:
There seems to be an implicit assumption here that fewer bytecodes is better.
But that isn't always the case.
Do you have evidence that the sequence
0 LOAD_CONST 5 ((('a', 'b', 'c'), 3, 2, 1))
2 UNPACK_SEQUENCE 4
is actually faster than
0 LOAD_CONST 0 (1)
2 LOAD_CONST 1 (2)
4 LOAD_CONST 2 (3)
6 LOAD_CONST 3 (('a', 'b', 'c'))
?
The second sequence has more bytecodes, but the first has to create a new
object.
I think you ought to be careful using the word "optimize" unless the output is
incontrovertibly superior.
